The Huang scattering distribution in reciprocal space near a fundamental (424) or a superstructure (212) reflection from a NiAl superalloy is characterized in this measurement of the diffracted intensity distribution as a function of X-ray energy. The area detector records the diffracted intensity in a spherical shell of reciprocal space whose radius is determined by the X-ray energy. From the Huang scattering it is possible to determine the local strain imposed by a coherent second phase that is distributed inside the super alloy crystal.
